Opposite of Chain Deweaving
Certain types of Atomic Chains have a tendency to tangle with each other. The degree of entanglement is determined by the types of Atomic Chains in question. This is a predictable phenomena with few inaccuracies. Normally this happens between two atoms or within the energetic half of an atom, and doesn't lead to anything abnormal.
Within some atoms the tangling of the energetic half causes Atomic Collapse. If an atom's Chain Reweaver compresses the Atomic Chains tightly enough then the Atomic Chains won't untangle as they rotate out of the Chain Reweaver. This process causes increasing tension outside of the Chain Reweaver. If there is relatively little tension, the Atomic Chains will knot up into a ball. If the tension is high enough, or increased rapidly enough, the Atomic Chains will break. In the case of broken Atomic Chains the atom will unravel into Free Chains.
Once Atomic Collapse occurs the atom becomes low energy. It is usually inert if it doesn't turn into Free Chains. It is possible for the atom in this state to go through Atomic Absorption if it runs into a sufficiently high energy atom. The chance to tangle with another atom though in nearly impossible as there isn't enough Atomic Chains to be reactive outside of the Chain Reweaver. On the rare occasion where a Atomic Chains has the space to tangle with another atom, the outcome is almost always that the Atomic Chains breaks from the tension. If this occurs enough it can loosen the Chain Reweaver enough for the atom to recover from collapse.
